Sig P365 Optic Cut - Sig Romeo Zero

(36 reviews) Write a Review

Add a Sig Romeo Zero Optic Cut as a standalone upgrade to your Sig P365 slide, or in conjunction with our other slide milling options.

This Optic Cut allows you to mount a Sig Romeo Zero sight directly to your P365 slide with two included #6-32 screws.

The cut features a precision CNC machined pocket directly in front of the Sig factory rear sight dovetail. By design, the Romeo Zero will fit tight within this pocket, preventing the sight from moving in any direction, ensuring your optic remains zeroed in even under the harshest conditions.

This product includes the Optic Cut only.

*Shield RMS not included.


This cut is also compatible with the Shield RMS/RMSc, but will use shorter screws.

    Really pleased with the work done. My Romeo Zero fit perfectly. The lead times were accurate and they are stellar to work with. Will use again for other customizations.

    Nice piece

    So far so good, sighting in was a breeze. It was out more than I expected, but a few rounds got it on the mark. This is my first red dot on a pistol, it takes a little getting used to. I had two other shooters at the range want to try it and one plans to send his to Maple Leaf for a red dot.

    Black Nitride / Romeo Zero

    Sent my Sig P-365 in to Maple Leaf to be milled and a Romeo Zero optic installed. The work was top notch, and the turn around time was fast. Thanks for the awesome work.

    Had to wiggle the optic to get it to seat because the fit was so tight. One thing I wasn’t aware of was that the zero optic shroud does not have the front mounting holes to fit the optic cut.

    I learned about Maple Leaf on the Sig forum and all the positive comments. Well my experience was everything that I hoped for! The work was excellent and the timeframe was exactly as quoted!

    Excellent work!! Had optic mounted just forward of rear sight. Very nice except am unable to co-witness front sight without suppressor sights. Highly recommend these folks ! Price was Very Good as well

    Sig P365 Set Back Mill for Holosun 507k X2 Red Dot sight

    Posted by Larron Clark on May 11th 2021

    The work was performed in a timely manner and the precision and quality of the work was way above standard. John is extremely helpful as I contacted him twice with questions and he was very accomodating and helpful. I will be sending them my Sig P320 to have the same service performed on it. I couldn't be happier!!!

    365 Romeo Zero Cut & Cerakote

    Posted by Michael Henry on Mar 28th 2021

    Most satisfied with Maple Leaf. Everything fit absolutely perfect. Cerakote is beautiful, but beyond aesthetics. This upgrade once sighted in, has drastically improved my speed of target acquisition & grouping.
    Exactly what I was trying to accomplish! Definitely eyeing my other pistols with "Ideas".

    Thx Maple Leaf Firearms

    Outstanding Quality

    Aside from not having holes all the way through the slide like the factory slide, you’d never know it didn’t come this way. Great job!
